DARIEN -- Police said current Darien High School students were not involved in Thursday's urination incident during the annual Thanksgiving Day football game against New Canaan.

Police received a report from Darien High after the game that someone entered the New Canaan locker room and urinated on players' property, Capt. Fred Komm said.

Komm also reported an equipment bag was stolen from the locker room.

Darien High School Athletic Director Mike Sullivan said as soon as school officials learned of the incident they conducted an investigation, which included reviewing surveillance tapes. He said once they determined that current DHS students were not involved, the surveillance tapes were turned over to the Darien Police Department.

Sullivan called the incident "an unfortunate and despicable event."

"It was a great game played by both teams, we had a big crowd, and it was a great day," Sullivan said. "It was unfortunate that an incident like that took away from the day."

Komm said because the investigation is ongoing, "he can't comment further other than to say that no current DHS students were involved with the incident at DHS."

Last year, a fight at an underage drinking party the Friday before the annual game hospitalized one Darien student and resulted in criminal charges against another. That student and a teammate were suspended from playing in the 2011 Turkey Bowl.

In 2010, the entrance way to New Canaan's Dunning Stadium was defaced with royal blue graffiti that read "D." The door handles to the school were defaced in an oil-based blue paint.
